GASRETORT STAND-PIPE.

SPECIFICATION forming part of Letters Patent No. 787,061, dated April 11, 1905.

Original application filed Ja a y 24, 1901, Serial No. 44,598. Divided and this application filed November 21, 1901 Serial No. 83,160.

Be it known that I, JOHN I'IAWLEY TAUS- sin, a citizen ot the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful improvements in Gas-Retort Stand- Pipes, of which the following is a specitica- To this and other ends hereinafterset forth the invention comprises three or more retortmouthpieces arranged verticallythe one above the other and connected together by sections of pipe which are arranged in line with each other and with a straight branchless standpipe.

The invention further comprises the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more full understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which Figure l is a front view of a bench of retorts. showing mouthpieees and stand-pipes embodying features of the invention; and Fig. 2 is a side view of the same.

in the drawings, 1, 2, and 3 designate retortmouthpieces arranged one above the other in a vertical line. in Fig. 1 three sets of these mouthpieces are shown: but the number of sets is of course unimportant, and while three retort-nuiuthpieces are shown in each set the number can be changed.

-t and 5 are straight sections of pipe which connect the mouthpieces, as shown, and these sections of pipe are arranged in a vertical line with respect to each other.

(3 is a straight branehless stand-pipe, which is arranged in line with the pipe-sections 4 and 5, so that the pipes 4, 5, and (3 are in a straight line and are themselves straight, so that there is a straight run of vertical pipe down through each mouthpiece; and they can consequently be easily cleaned-for example, by means of the apparatus described in my said application or by means of any suitable instrument.

For upward of at least tifty years and in cases where in a setting there was not sutlicient room to provide each mouthpiece with a separate stand-pipe it has been the custom to connect the retorts in pairs with standpipes of which those at the top were straight and the others curved. This was done simply for lack of room, and in. such settings the stand-pipes were cleaned by inserting a tlexible rod through the retort-mouth and up into the stand-pipe. inasmuch as the presence of curved stand-pipes necessitated the working of the rod up through the retortmouthpieces, so far as cleaning was concerned it made no ditlerence whether the stand-pipes were straight or crooked. To work the rod upward through the standpipes exposed the workmen to the heat of the open retorts. They were frequently overcome by it, and the resistance offered by the curved standpipes to the passage of the cleaning-tool was such that great labor was required to push it through them. Contrasted with this the described arrangement or combination contemplates cleaning from So the top of the stand-pipes in a location where it is cool and in a way that does not require any great or special ctl'ort on the part of a single workman, who may use a rigid tool.

it will be obvious to those skilled in the art to which my invention relates that modifications maybe made in details without departing from the spirit thereof. llence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the ruicompanying drawings; but,

Having thus described the nature and objects of the invention, What I claim as new, and desire to secure by Letters Patent, is-

In apparatus for the manufacture of coalgas the combination of a stack of retorts comprising a plurality of benches each containing vertical rows or sets of non-communicating retorts having their mouthpieces in vertical alinement, a series of vertical paral- 10 lel stand-pipes each one of Which is straight throughout its length and is connected With the top mouthpiece of a vertical row or set of
